  • a BMS, breast milk sample.

  • b A sample was considered positive (shaded) if the ID50 was greater than 3 times the SVA-MLV background and greater than 3 standard deviations above the mean of the HIV-negative control samples. All negative controls from plasma had ID50 values of <20.

  • c The mean ID50 of uninfected milk controls plus 3 standard deviations.
